dellsmaith, your post has nothing to do with the original topic, don't hijack threads
SparkFun is also not the appropriate place for general Java questions, I would suggest StackOverflow for that. But, since I'm weak at heart, I would suggest you
a) Install the JDK (not just the JRE)
b) Make sure the JDK is in your PATH
Which should solve your basic computer issues with commands not being found.
